Simple Lithium ion Lipo Battery Charger Electronics DIY This is a Lithium ion charger for lipo batteries. Circuit schematic shows configuration for charging single 3.7V lipo battery but voltage can be set to charge several batteries in series. Lipo charger sets a current limit with the LM317, and 1 resistor, and the voltage limit with the TL431, and 2 resistors. 1K resistor is needed to let the TL431 decrease the LM317 current, and to provide the ... Intelligent NiCd NiMH Battery Charger Electronics DIY This cheap and easy to build NiCd NiMH Battery Charger is suitable for automatically charging a wide range of batteries for many applications. Proper chargers are usually expensive and cheap chargers supplied with the original equipment often incorrectly charge the cells and dramatically shorten their life. This 'intelligent' charger was designed for high current and rapid charge applications ... cdselectronics 12 V BATTERY TESTER. INSTRUCTION SHEET . Price Stock No 550. Description.
